SHIPPING MILK-CAN.

SPECIFICATION forming part of Letters Patent No. 293,682, dated February 19,1884.

Application filed December 6, 1883. (No model.)

To all whom it may concern:

Be it known that I, J OSEPH Frswan, a citizen ofthe United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Shipping Milk-Cans, of which the following isa specification, reference being had therein to the accompanying drawings, in which- Figure 1 is a central vertical section of the can and float. Fig. 2 is a perspective view of the can. 8 is a perspective view of the float, and Fig. 4 a vertical sectionof the same.

My invention relates to improvements in cans and floats used in the transportation of milk, and is related to the devices shown in tagonal shape, and made of wood, and apacking of suitable non-conducting material, D, is interposed between the can and casing. VVithin the lower end of the casing is placed the wooden bottom E, having an octagonal periphery or corresponding with the form of the casing.

To retain together the lower end of the staves forming the casing, and also the bottom E, a polygonal band or hoop,F, of heavy tin or sheet metal, is used to surroundsaid staves.

The lower half or third of. the hoop F is slitted at the angles corresponding with the joints of the staves, and the segments ll" thus produced are flanged inwardly, and the two adjoining edges produced by the slits above stated are made to overtop each other, as shown at f, toproduce a double thickness of sheet metal at these points, projecting beyond the flange of the adjoining segments and protecting it against abrasion when the cans are of the temperature.

dragged upon the ground. The. two thicknesses of sheet metal are soldered together at f, and the wood bottom E and flanged segments F are thus retained securely until the metal is worn out. If desired, nails orscrews f may be driven through the hoop F into the staves and the bottom of the casing as additional security. The upper hoop, B, is formed in an inverse mannerthat is, with a smooth and level top-4011b the segmental sides are reenforced at the angles of the casing. For this purpose an annular disk of sheet metal is used, in the outer periphery of which a slit is made to correspond with each angle of the casing, and'after having folded each segment so as to rest against one of the staves, one of the edges. of the slits is bent laterally, and the triangular piece I) thus obtained is bent under the adjoining edge of the slit and soldered thereto, forming a strong connection between the segments at that point. The inner edge of the disk is bent upward at 12 to support the flanged edge a of the inner vessel, A. The cover G, to close the latter, has a cylindrical portion, 9, that fits within the mouth of the vessel A, and also a bottom disk, g, and an upper disk, 9 The latter, extending beyond the cylindrical portion 9, rests upon the flanged edge of the inner vessel. An air-chamber, G, is thus formed within the cover,.to render the contents of the vessel less subject to changes The cover is also provided with a central opening, 9?, to either ventilate the interior of the vessel or receive milk from a suitable funnel. At other times the opening 9' is closed by a small cover, G pivoted upon a bolt, 9 passing throughboth disks of the cover and through a small blockof wood, fitting between the disks in their central portion, to prevent said disks from being so compressed together by the nut upon the bolt 9* as to become strained and deformed. The cover is provided with handles 9 to facilitate its removal from the can when desired.

WVithin the vessel A is placed the float H.

with, is a second cylinder, h, the diameter and v height of which is about half as large as the cylinder It. The upper edges of these cylinders are united by an annular flaring cover, h", soldered thereto, so as to produce air-tight joints with the upper edges of both cylinders and form of its upper surface a conical funnel, to direct milk poured upon it from the circumference toward the central opening, and the latter opening is provided with a cover, 7.", preferably coneishaped, with its apex uppermost, and said cover is secured to the inner edge of the flaring funnel If. The central cover, k, is constructed offine wire-gauze or of perforated sheet metal, to allow milk to pass downward therethrough and air upward through the center of the float, and at the same time prevent flies and foreign substances from entering or falling in the milk contained in the can. Handles m are secured to the top of the cover 71? of the float, to facilitate its being lifted from the can. By this construction of the float an air-chamber, H, is produced under the cover if, between the two concentric cylinders, that gives to the whole a light specific gravity, and causes the device to float upon the milk and prevent its splashing, agitation, and churning often produced while under transportation. The air-chamber H can have its lower portion open, as shown in Fig. 1, or closed, as shown in Fig. 4, the effect being substantially the same.

By having the central cover, k, perforated, as above stated, the float need not be removed from the can before filling the latter, as the milk can be poured upon the float, and, although temporarily submerging the latter, it will pass through the perforations of the cover k and descend under the float, and consequently no care need be exercised or attempt be made to pour the milk in the center only, as the flaring funnel h extends from the periphery of the can and directs the whole volume of milk toward the central screened opening.

and for the purpose described.

2. The combination,with the polygonal wood casing and bottom of a milk-can, of the lower hoop, F, of sheet metal, having its upper portion formed with angles corresponding with the wood casing, and its lower portion slitted and bent under the bottom of the casing, and one end of each turned-under segment overlapping the end f of the adjoining segment, substantially as and for the purpose described.

3. In a transportation milk-can, afloat composed of two concentric cylinders, the inner one of less depth than the outer one, an airtight cover extending from the top edge of the outside cylinder inward and downward to the top edge of the inner cylinder, anda perforated cover secured over the central opening of the inner cylinder, substantially as and for the purpose set forth.

4. The combination of the concentric cylinders h h, of different length, the flat annular disk uniting them at the bottom, the flaring annular cover uniting the upper edges of said cylinders, and the perforated cone (Z over the inner cylinder, whereby a milk-can float is produced, to operate as set forth, for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
